A wood plaster ground IS is adapted to be mounted adjacent the wall 2| between the arms 24 and 25, after which the ends 21 and 2B are then bent against the outer face I1 of the plaster ground I6' to form locking tabs, after which the plaster wall 29 is applied. The brackets are formed of flexible and perforable material. In Fig. '7 the arms 5 and 6 are shown as of a length substantially equal to the thickness of the plaster ground I6, and nails I 8 driven therethrough into the plaster ground. If desired perforations may be formed in the arms prior to installation of the brackets to facilitate locating and driving the nails into the plaster ground. The leg l 2 is shown of a length greater than the bight portion 9 to facilitate sliding of the bracket thereon should one of the openings be misaligned. In Fig. 8 is shown a further modified form wherein the supporting units are adapted to connect a sheet metal plaster ground. In this form the bight portion 32 is perforated at 33 adjacent the inner arm 34 of the U shaped brackets 35. The connectors i are adapted to clamp the arm 34 against the face l of the slot 2' in the tile wall I with the bight portion 32 in a horizontal position. A U shaped metal plaster ground 36 is f adapted to be mounted upon the bight portions 32 and is provided with an S shaped outer portion. The outer arm 31 of the bracket 35 is adapted to be arranged between the walls 38 and 39 of the S shaped portion, whereby to connect the plaster ground to the wall l; after which the plaster wall 40 is applied. From the foregoing it will be seen that I have provided a simple supporting means for plaster grounds which is economical in manufacture and installation and wherein no nails are needed, the device having been installed in practical use with a great saving in cost of labor and time.

Having thus described my invention, what I claim is:

1. A device of the class described including, in combination, a wall, a staple having one leg thereof imbedded in said wall, a plaster ground, and a U shaped supporting member adapted to receive said plaster ground, said supporting member having the bight portion thereof in abutment with said wall and having aligned openings in the legs thereof, the other leg of said staple adapted to be arranged in said openings and hav--` ing a hook on the end thereof adapted to support said supporting member.

2. A device of the class described including, in combination, a wall, a staple having one leg imbedded in said wall, a plaster ground, and a fiexible U shaped strip of material adapted to receive said plaster ground and having openings in the legs thereof adjacent its bight portion, the other leg of said staple adapted to be arranged in said openings and having an outwardly turned portion adapted to support said strip.

3. A device of the class described including, in combination, a wall, a staple having one leg thereof imbedded in said wall, a U-shaped supporting member having openings adapted to slidably receive the other leg of said staple, and a plaster ground adapted to be mounted in said U shaped supporting member.

4. A device of the class described including a staple having a hook formed on one leg thereof, and a U shaped supporting member having perforations therein adapted to slidably receive said leg.

5. A device of the class described including, in combination, a plaster ground, a staple having an outwardly bent portion on one leg thereof, and a U shaped iiexible strip of material having aligned perforations adapted to slidably receive said leg and having opposed fingers formed on the outer ends thereof, said ngers being adapted to hold said plaster ground in position.

6. A device of the class described including, in combination, a staple having an inner and an outer leg, and a perforated U shaped flexible supporting member having an upper and a lower leg, said outer leg adapted to be mounted in the legs of said supporting member adjacent the bight portion thereof and having an outwardly turned end portion adapted to support said supporting member.

'7. A device of the class described including, in combination, a staple having an inner and an outer leg, and a perforated U shaped flexible supporting member having an upper and a lower leg, said outer leg adapted to be mounted in the legs of said supporting member adjacent the bight portion thereof and having an outwardly turned end portion adapted to support said supporting member, said upper and lower legs being bent inwardly in opposed relation at their outer ends.
